Genomics as Only One of Multiple Precision Medicine Methods
Within the overarching trend towards personalized medicine, many corners of medicine have fast-embraced genomics. However, it is only ONE piece of the puzzle when it comes to truly individualizing patient care. Too often, I see patients who have been told that they have a certain gene mutation and that it alone has responsibility for certain health outcomes. The reality is most often much more complex and multifactorial. The New England Journal of Medicine tackles this tension in its most recent issue, in the context of public health personalization (historically a dichotomous head scratcher!): “The more tightly defined and individually focused conception (of personalized public health), anchored in genomics, has gained greater momentum – and poses a greater threat.” Read more at the NEJM and here: The New Nutrigenomics – Embracing Complexity, Moving Upstream.

Scientists Argue for Microbiota ‘Vault’ to Protect Long-Term Human Health
Should we be creating a human microbiota ‘vault’ to protect our long-term microbial diversity and health? Scientists at Rutgers University think so. Underscoring just how important our microbiome(s) are – digesting food, producing nutrients, strengthening our immune system, protecting against pathogens, balancing our metabolism, producing cancer-protective compounds, and more – this ‘global repository’ would be akin to the Svalbard Global Seed Vault, the world’s largest collection of crop diversity created in case of natural or human-made disasters.

Flaws in the Lancet Meta-Analysis of Vitamin D for Bone Health
Classical scientific research models aren’t perfect when it comes to assessing nutrition. A recent Lancet meta-analysis (an analysis of many different trials) concluded that vitamin D has no benefit for bone health. But, as this rebuttal explains, looking at nutrients in isolation misses the vitally important fact that nutrients work together for health outcomes. Vitamin D is needed for calcium absorption, but you also have to be consuming enough calcium in the first place, and you also need vitamin K to ensure that the calcium is deposited into bones (instead of soft vascular tissue). Other nutrients are involved too. While we continue to need good scientific study of nutrients, we need a more comprehensive way to assess real-life nutrient interactions. Combination studies may prove more valuable.

Benefits of Ketogenic Diets Mediated via Gut Microbiome
Supervised ketogenic diets can be an incredibly powerful therapeutic tool. Several mechanisms are at work with ketogenic diets, but not all are well understood. New research highlighted in the JAMA news networks indicates that the gut microbiome may be pivotal in mediating some of the beneficial effects of the diet. Yes, gut microbes are altered with a ketogenic diet – most notably an increase in Akkermansia species. These microbial changes are associated with decreased gamma-glutamyl amino acids and elevated GABA/glutamate levels in the hippocampus, and reduced seizures in mouse epilepsy models. It’s reasonable to think that these microbially-mediated effects may be behind some of the benefits seen for other disease status such as cognitive decline.

Proceeds from Health Data Sales Could Soon Come to You
If you, like many of us and our patients, have paid for your own 23andme genetic report, you will have clicked-to-agree that 23andme can sell on your anonymized data and reap the proceeds from that. In other areas, other deidentified medical data is also brokered to third parties from health care providers, pharmacies, insurers and clinical labs. To who? Pharmaceutical companies and other businesses who use that aggregated data for research, product development and marketing purposes. Eric Topol, from the Scripps Research Institute, thinks that data ownership (and payment flows) will change in the future, allowing consumers to get in on reaping the proceeds from health data markets too. He points to a growing group of health data brokering startups, called ‘biobrokers’, who’s goal is to shake up the industry and transfer data control (and a share of the profits) back to the individual. Do you believe you should own your data?

Do ApoE4 Brains Have a Harder Time Utilizing Glucose?
ApoE4 gene variants are associated with an increased risk for Alzheimer’s Disease. New animal research suggests that this gene variant may impair the brain’s ability to utilize glucose, since it is associated with a reduction of a key glucose-metabolizing enzyme, hexokinase. It makes an interesting potential argument for the use of ketogenic diets in Alzheimer’s disease, especially since, in this study, ApoE4 carriers retained normal levels of ketone utilization proteins. ApoE3 carriers, meanwhile, had lower level of ketone utilization proteins. More on preventing and reversing cognitive decline here.

It’s time that we, practitioners, re-consider the approach that ‘pushing’ methylation reactions with supplementation alters epigenetic methylation expression. In their new eBook, Fitzgerald and Hodges explain how to support epigenetic and metabolic methylation. Learn how to support methylation the RIGHT WAY with The Methylation Diet and Lifestyle — a smart, safe plan that includes diet, exercise, gut health, stress, resilience, sleep and ways to limit “methyl donor drain.

The central role that methylation plays demands more careful attention than simply reaching for supplements. That’s why I’m excited to incorporate the ideas from the new eBook for cliniciansThe Methylation Diet and Lifestyle into my own practice. In this book, Dr. Fitzgerald and Romilly Hodges explain how to use a broader and safer approach to healthy methylation expression, including diet, limiting methyl donor drain, stress response, exercise and gut health. It’s a must-read!

I LOVE LOVE LOVE your new ebook, Methylation Diet & Lifestyle! It’s brilliant! Kara and Romilly make a complex biochemical subject easy to understand. I love your explanation of methylation, the nuance and distinctions like considering the complex interplay among the SNPs, the needed nutrients, and the food recommendations! It’s a must read for practitioners and patients.” – Certified Nutrition Consultant and Author of Nourishing Hope for Autism.

These days, methylation is a ‘hot’ topic in functional medicine: everyone knows it’s important, but there is debate about which is the most effective clinical protocol is for the best outcome. What I like about the Methylation Diet and Lifestyle E-book is that it takes a whole-self, lifestyle-medicine approach to this complicated area of clinical medicine and makes it actionable for the millions of us with variability in our ability to detoxify through methylation. This 140-page report is grounded in practical steps to get those with methylation deficits on their way to feeling empowered and healthy.

Dr. Fitzgerald’s book is an extraordinary integration of a vast amount of diverse information that makes practical sense of the complex interplay between our genes, the folate/vitamin B12 cycle, homocysteine, and the clinical importance of methylation.

The Methylation Diet and Lifestyle Book contains “news to use” that makes the very complex human biochemistry story of methylation reader friendly. It is a wonderful introduction to how nutrition and lifestyle can influence the epigenetic regulation of gene expression.

Finally, an easy to read and understand explanation of methylation that is suited for both clinicians and the public. In Methylation Diet and Lifestyle, Dr Kara Fitzgerald demystifies the genetics and offers a rational approach that steers away from high dose supplementation as the answer, and instead focuses on using food as medicine. Thank you for bringing balance to this conversation!

It takes a special skill to be able to make the complex understandable and accessible without losing the original essence. Kara has that skill in abundance and her Methylation book is a latest shining example. She has a rare gift to impart the tenets of Functional Medicine and produce brilliant guides and case studies, and in this field I have been fortunate to learn more from her writings and lectures than from any other professional. I have been involved with nutrigenomics professionally for a number of years, and I can honestly recommend this book wholeheartedly no matter how experienced the reader. This is a book that works on many different levels and is representative of standards that all writers in the genre should aspire to.

This book provides the tools you need to make an important contribution to your health, by understanding and applying the nutritional and lifestyle factors that impact the methylation process in every cell of your body.
